In the present work, a borosilicate glass was coated with ceramic films by a radio-frequency (RF) magnetron sputtering method, and roughness and hardness were measured as surface characteristics of coated glass. A new procedure to estimate the strength of coated materials was proposed by incorporating relative hardness and roughness with sputtering time. The strength in experiments was well estimated by using the proposed procedure. Minimum fatigue life of each coated glass was well expressed as a power function of the mean strength.

本文采用射频磁控溅射法在硼硅酸盐玻璃表面涂覆陶瓷膜，并测量了涂层玻璃表面的粗糙度和硬度。提出了一种将相对硬度和粗糙度与溅射时间相结合来估计涂层材料强度的新方法。用所提出的方法可以很好地估计实验中的强度。每个镀膜玻璃的最小疲劳寿命可以很好地表示为平均强度的幂函数。
